LAYBOY.

Application iled March 12, 1913.

To all 4whom it may concern.'

Be it known that I, JOSEPH A.. IHITE, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Layboys, of which the following is a specification.

My invention relates to certain improvements in lay boys used in pilingsheets of paper after they have been cut or printed.

The object of my invention is to construct the lay boy so that theplatform carrying the paper will be suspended from an overhead frameworkto allow for the insertion of a truck under the platform and to allowfor the free access of the operator to the pile of paper during theoperation of piling.

The invention also relates to the means whereby the platform can bereadily detached from the means by which it is suspended so that itcan-be quickly removed from the machine.

In this application I lay no claim to the mechanism for piling thepaper.

In the accompanying drawings: Figure 1 is a sectional view of a lay boyillustrating my invention; Fig. 2 is a diagrammatic per* spective viewshowing the platform in dotted lines with the truck located in positionunder the platform; Fig. 3 is an end view of the platform and carryingbar; Fig. Ll is a detached perspective view of a detail;-Fig. 5 is aview of a modification of the suspending means; and Fig. 6 is anenlarged portion of Fig. 1.

Referring to the drawings, 1 is the frame of the lay boy.

2 is the platform upon which the paper is to be piled.

V3 is the overhead frame, projecting from the main frame 1 asillustrated in Fig. 1, supported by a. post l at each side of themachine or suspended from a beam 5, as illustrated in Fig. 5 so as toleave all of the space or a portion thereof under this overhanging frameclear for the paper and to allow for the examination and sorting of thepaper by the operator. The posts 4-4C may be close to the machine orthey may be arranged some distance from the machine, depending upon thelocation of the lay boy in reference to other machines or other posts inthe building.

6-6 are two longitudinal shafts, one at each side of the machine andadapted to suitable bearings 7 secured to the overhead frame 3. On eachshaft are two chain drums Specification of Letters Patent.

serial no. 753,815.

S-Sa and from these chain drums are suspended chains 9 and 10respectively. The chain 9 is attached at its lower end to a beam 11adapted to guides 12 in the main frame 1, while the chain 10 has a ring13 at its lower end through which passes the end of the bar 14, which ispreferably grooved at 15, as shown in Fig. 3, so that the ring will fitin this groove and will prevent the bar from moving longitudinally. Theplatform 2 is carried at its'inner end by the beam 11 and at its outerend by the bar 14:.

16 is a transverse shaft adapted to bearings in the frame 1 and on thisshaft are two worms 17 which mesh with worm wheels 18 secured to eachshaft 6. The shaft 16 is the driving shaft and imparts motionthrou ghthis gearing to the two shafts 6 so as to lower the paper as the pileincreases in height. In an application for patent filed by me on the10th day of August, 1911, Serial No. 643,325, the mechanism foractuating this shaft is controlled by the paper closing the air passageleading to the pneumatic operating mechanism which automatically lowersthe pile of papers as the pile increases. rIhe mechanism in the presentinstance is con trolled by the fingers resting on the top sheet of paperof the pile so that, as the pile increases, the fingers releasemechanism which causes the shafts to turn and to lower the platformcarrying the paper a certain distance.

19 is a transverse rock shaft having fingers 2O which rest on the topsheet of a pile of paper. On the end of this rock shaft is an arm 21counterbalanced by a weight 22 so as to make it sensitive.

23 is a lever pivoted at 24 and has an eye through which the arm 21extends. The short arm of this lever is connected to a spring 25 so asto cause the arm to move away from the rock shaft 19. Pivotally mountedon the large arm of the lever 23 is a pawl 26 which is arranged toengage the ratchet teeth on the wheel 27 secured to a shaft 2S and onthis shaft is a sprocket wheel 29 around which passes a drive chain 30which also passes around a sprocket wheel 31 on the shaft 16 so that anymovement imparted to the shaft 28 will be transmitted to the shaft 16and to the platform 2.

32 is a driven shaft having an eccentric 33 on which is mounted a block34: attached to an arm l5 pivoted at 35 to the frame of the machine.This block has an oscillating movement due to the eccentric.

IV hen the pile of paper is at its normal height, then the lever 23 isoutside of the path of the block 34, due to the fact that the arm 31 onthe rock shaft holds it out of position, but when the pile of paperincreases in.v height, it lifts the fingers 20, which rock th'e'shaft19, and releases the lever 23 and its spring 25 forces it into the pathof the block 34. This block is moved laterally, which causes the pawl 26to move and to push the ratchet wheel forward a number of teeth, causingthe platform 2 to be lowered and when the top of the paper is again atthe normal height, then the arm 21 again engages the lever 23 and holdsit out of the path of the block 34. The paper is fed to the pile bymeans of two endless belts 36 and 37.

The construction of the feeding mechanism will depend upon the characterof the machine to which the lay boy is attached.

In Fig. 5, I have illustrated a modification of the invention in whichthe vplatform 2 rests upon two detachable bars 14 which are suspended bythe two chains 9a from the two shafts 6a and when the platform 2 islowered on to the track 38 then both bars 14a are removed.

In the construction illustrated in Fig. 1, only one bar 14 is removed,the beam 11 being lowered to a position clear of the platform, when theplatform is on the truck.

In Fig. 5, I have shown the overhead frame 31 suspended from a beam 5instead of being supported by the vertical posts 4. This beam may besupported in turn by posts or may form part of the overhead structure ofthe building in which the machine is mounted.

The jogging mechanism, Fig. 1 for lreep-l ingrthe sheets of paper in theproper position on the pile consists of a bar 39 located at each side ofthe machine, having arms 40 to which are secured the plates 41 whichextend on each side of the pile of paper. The joggers are movedlaterally so as to pile the paper evenly on the platform. At the end ofthe machine is a stop 42 and side guides 43 suspended from a frame 44longitudinally adjustable in the overhead frame 3.

The operation is as follows: It is desirable to have the top of the pileof paper always at the same height so that sheet after sheet of papercan be laid upon the pile at the same point. The platform 2 rests uponthe two beams or cross bars which are suspended from the overheadstructure by chains or ropes and these chains pass around drums onshafts which are turned in unison by mechanism previously described,which is turned in the present instance by the fingers resting on thetop of the paper so that as the paper increases in height the mechanismwill be thrown into operation and will automatically lower the platform.When, as in Figs. 1, 2 and 3, the predetermined height of the pile ofpaper is reached, then the platform 2 is lowered on to a truck 38 whichis located directly under the overhanging structure and the bar 14 isdetached from the chains 9 and removed soA that the truck, with theplatform and the pile of paper thereon, can be readily removed fromunder the overhanging structure at the front or at either side and thecross bars 14 replaced and another' platform placed in position.

By making the over-hanging structure, as shown, not only can the truckbe readily moved under the structure, but access may be had t0 the pileVof paper from either side to remove imperfect sheets, when necessary.

I claim:

The combination in a lay-boy, of a frame; an extension at the upper endof the frame; means for supporting the extension independent of theframe and some distance from the outer end thereof; Vtwo longitudinalshafts, one on each side of the extension; a transverse shaft geared tothe longitudinal shafts; means for actuating the transverse shaft; drumsat each end of each longitudinal shaft; chains depending from the drums;a cross bar secured to the lower end of each inner chain; a cross bardetachably secured to the outer ends of the outer chains; Aand aplatform carried by the cross bars.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. Y
